The invention;is'directedjto an improvement in electricfdespatch systems and the .general Object ofthe invention is to expedite a ':the transportingof mail from the post-office to theg pvarious points ofs. destination on a rural-route, and to facilitate andfexpeditef the 3 delivery and collecting oftthe mailat various points on-the said route and .to this end the invention 'consistsin ctartain imi proved constructions, arrangements, and combinations of devices, which will be? fullydescribed hereinafter, and then pointed out i Yi' Other, objects (will; appear and be. better I g HIIdGIStOQdgfIQIH that embodiment of m'y-inin the claims. j;

The arms, (ifwhichfare.suitably connected at one end tothe upper endportionsj ofthe poles 5, are of suitable material such as.,1netal and maybe of any convenient length. The brackets 7-7 which depend fromland are suitably secured to the arms 6,

are of suitable material such as metal, and

of any convenient'eontour such as right angular.

The track rails 8-.8, which are suitably connected tothe adjacent ends'of the brackets 77, are of metal and preferably grooved" longitudinally in their upper and lower sides as'indicated at 9-9. l
